VAPOR-TUBE HEATERT SPECIFICATION forming part of Letters Patent No. 650,899, dated June 5, 1900.

Application filed March 20,1899. Serial No. 709,812. (No model.)

. To all whom it may conccrnw Be it known that I, ARTHUR KIT-SON, a subject of the Queen of Great Britain, and a residentof Philadelphia, county of Philadelphia,

State of Pennsylvania, have invented certain new and useful Improvements in Vapor-Tube Heaters, (Case No. 33,) of which the following is a specification.

My invention relates to vapor burning {O lamps; and it consists of an improved arrangement of Bunsen burner and pilot-light for starting said lamps into operation.

The preferred form of my apparatus is illustrated in the accompanying two sheets of r 5 drawings, in which Figure l is a horizontal section, looking down, on line 11 of Fig. 2. Fig. 2 is aside elevation and partial section of the lamp with my improved Bunsen burner attached. Fig. 3 is a second elevation at right angles to the plane of Fig. 2.

Throughout the drawings like reference-figures refer to like parts.

The lamp shown has the ordinary main frame 1, in which is mounted the horizontal vaporizing-tube 2. ing tube and preferably to one side and slightly below the same I arrange the Bunsen burner 23, which has its end 4 closed and a series of perforations 5 or a slit on the side adjacent to the vaporizing-tube and so located that the jet or jets issuing therefrom will impinge on the vaporizing-tube. Preferably I have said discharge-openings point slightly 5 downward, so that the flame will be carried down and then up, entirely surrounding the vaporizing tube. Below the Bunsen burner and adjacent to one of the discharge-orifices is located the pilot-light 6.

0 Gas is supplied to the pilot-burner by a tube 8 and to the Bunsen burner by a second tube S. Oil is supplied to the vaporizing-tube by a tube 9 and the supply controlled by a Valve 10. The oil andgas' tubes may be conducted 5 through a tubular suspension-rod 11.

The mode of operation of my invention is obvious from the foregoing.

The pilot-burner 6 burns continuously with Parallel to this 'vaporiz-- a small flame. On turning the gas on to the Bunsen burner 3 the ordinary mixture of gas so and air is formed by means of air drawn in through the adjustable opening 7 and the mixture issues from the orifices 5, is ignited by the pilot-burner, and bn ms in a blue flame, which is carried up by the current of hot air in the direction shown by the arrows and so bathes completely the entire length of the vaporizing-tube and quickly raises the same to the temperature necessary to vaporize the oil when the same is admitted. After this the gas is shutoff the Bunsen burner and thelamp continues to burn vapor in the well-known manner.

It is evident that various changes could be made in the details of construction illustrated 6 5 without departing from the spirit and scope of my invention so long as the relative arrangement of parts shown in the drawings or the principle of operation described in the specification is preserved. The position of 7c the Bunsen burner might be varied slightly so long as the flame was caused to impinge onthe vaporizing-tube. The character of the discharge-openings might be changed. Other modes of supporting the Bunsen burnermight be employed, 850.; but all these I consider changes of form and not of substance and still within the scope of my invention.

Having therefore described my invention, what I claim as new, and desire to protect by Letters Patent, is

1. In a vapor-burning apparatus the combination. of an oil-supply pipe, a vaporizingtube connected thereto, a gas-supply pipe, a Bunsen burner comprising a tube parallel to the vaporizing-tube and connected to the gassupply pipe, and provided with one or more openings so located that jets of flame projecting therethrough will impinge on the vaporizing-tube. 9o

2. In a vapor-burning apparatus the combination of the main frame, the horizontal vaporizing-tube therein, the Bunsen burner comprising a tube arranged parallel to the vaporizing-tube, said burner having its end 5 closed but provided with one or more dis- 4. In a vapor-burning apparatus, the com bination of the Vapor-burner and oil-supply pipe, at vaporizing-tube connected thereto, a gas-supply pipe, and a Bunsen burner separate from the vapor-burner connected to the gas-supply pipe, and so located that the flame from the Bunsen burner impinges on all parts of the vaporizing-tube exposed to the flame of the vapor-burner.

Signed by me at New York city, New York, this 11th day of March, 1899.
